So, I played all 40 levels and solved all of them except 35. It has some really great levels
1: Really great use of bribes. My bonus was 1000.
2: I like it, it's clever.
3: Hooks are awesome.
4: This one was much harder than the previous ones. I like the concept, and it proves that item dropping is not entirely bad.
5: It was a fun level. The four puzzles were all well-designed.
6: Took me way too long to figure out the bowling ball trick. Fun level, I got the full 1100 bonus.
7: One of the most creative mazes I've seen in a long time.
8: It's shorter than the last few levels, but that's the perfect length. Creative concept.
9: A nice way to include both Chip and Melinda. The item exchange at the end is clever.
10: It's a decent level, but rovers remain the worst tile in CC2.
11: It's a fun level, the various rooms fit in well together. Final bonus 450.
12: One of my favourite levels so far. Final bonus 1100.
13: It took me forever to figure out how track switches work with the R&R sign. It's a clever puzzle though, and I got the full 14 000 bonus.
14: The bomb trick in the first room is very clever. The following puzzles also work nicely. I got 4660 bonus.
15: Creative concept.
16: Took me forever to figure out the mimic trick. There are some clever puzzles here.
17: Very easy, I solved it and got a bonus of 6600. Perhaps the time limit could be shorter?
18: Very nice, I especially like the ghost and ice block rooms. I got the full 2900 bonus.
19: Decent level. My bonus was 1400.
20: More interesting hook puzzles. My final bonus was 60.
21: Really clever puzzle, and I got the 400 bonus.
22: Fun puzzles and nice aesthetics.
23: It's an all right level. The concept is clever, although not one of my favourite levels so far.
24: Fun ghost puzzle, although it is a bit creepy how you end up murdering Casper in
cold blood a hot flame jet to exit
25: A really interesting blob level. I solved it, but didn't try for the bonus.
26:
Melinda goes on a killing spree it's actually a very fun level with clever puzzles.
27: Really fun. Didn't get the bonus though.
28: Decent level, although not one of my favourites. My final bonus was 1200.
29: Fun puzzles, and really great aesthetics.
30: Great puzzle. The ice block/transmogrifer trick is awesome.
31: Really interesting puzzle. Unfortunately, I wasn't able to get the bonus.
32: I remember this level from the original version; don't think I solved it then though. I solved it now, and it was really fun. My final bonus was 2250.
33: It took me a while to figure out the tricks. This is very clever.
34: Fun puzzle.
35: This appears unsolvable. I can't figure out how to make it past the dynamite explosion; while it is true that recessed walls don't pop up if dynamite is placed on them, it's of no use after said recessed wall turns to fire.
36: Much harder than it looks, but really fun.
37: Interesting use of swivels. I got a bonus of 500.
38: Really great level, fun puzzles and creative sokobans, nice use of yellow teleports. For some reason throwing the bowling balls into them erases one, but that doesn't alter solvability.
39: This concept is absolutely amazing.
40: Fun level, although I had to use Tyler's video to solve it. A bit disappointing you removed the wall slapping trick though, but it's still a great level. My bonus was 2240.
